I am a QA Engineer with over 4 years of experience in manual testing, automation and quality assurance. I have worked with UI, API and design testing, created test cases in Gherkin, analyzed them through Jenkins and interacted with development teams and product owners. I use tools like Jenkins, Jira, Confluence, Zephyr, IDEA, Postman, Mailtrap, Miro, Figma, GCloud, Swagger. I help find critical bugs before release to ensure the product is stable and safe for users. I have experience in fast and accurate data entry, which saves the team time and reduces the risk of errors. I also perform transcription and annotation, ensuring high-quality processing of information for clients. My work combines attention to detail with a practical understanding of business goals, so I can be useful in both testing and data or content management tasks.

What does a Katalon Studio freelancer do?

A Katalon Studio freelancer builds and maintains automated test scripts for web, mobile, and API applications using the Katalon Studio platform. This specialist translates manual testing requirements into repeatable automation code that verifies software functionality without human intervention. They structure test cases into organized suites and create reusable custom keywords to reduce redundancy in testing logic. The freelancer connects these automated tests to continuous integration pipelines and issue tracking systems to keep development teams informed of software quality.

  • Authors automated test cases and organizes them into test suites within Katalon Studio to cover functional and regression testing scenarios. The freelancer uses object spy features to identify UI elements and writes Groovy-based scripts to define user interactions such as clicks, form submissions, and data validation checks. They group related tests into suite collections to execute specific batches based on release cycles or feature updates.
  • Develops custom keywords in Java or Groovy to encapsulate complex testing logic and promote code reuse across multiple test cases. Instead of repeating identical steps in every script, the freelancer creates modular functions that handle common actions like database connections, API calls, or dynamic data handling. These keywords simplify test maintenance because changes to underlying logic require updates in only one location rather than dozens of individual test scripts.
  • Configures integrations between Katalon Studio and external tools such as Jira, GitHub, and Jenkins to automate the flow of test results and version control. The freelancer sets up repository links so test assets sync with source control systems, allowing multiple team members to collaborate on test development without overwriting each otherโ€™s work. They also establish connections to CI servers to trigger automated test runs whenever new code is committed, ensuring immediate feedback on software stability.
  • Executes test runs via Katalon TestCloud or local environments and analyzes execution logs to identify failures and root causes. The freelancer distinguishes between genuine software defects and flaky tests caused by timing issues or environment instability, then adjusts scripts to improve reliability. They generate detailed reports that highlight passed and failed steps, attaching screenshots or video recordings to help developers reproduce and fix identified bugs quickly.

How to hire a Katalon Studio freelancer on Upwork

Step 1: Post a job

Define your automation needs clearly to attract qualified specialists. Use the Job Post Generator powered by Umaโ„ข, Upwork's Mindful AI to draft a precise description in seconds. Describe your testing requirements in a few sentences, and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify whether the freelancer must build web, mobile, or API test cases within Katalon Studio.
  • List required integrations, such as connecting test results to Jira or triggering runs via Jenkins.
  • State if the role involves creating custom keywords in Groovy or maintaining existing test suites.

Step 2: Evaluate candidates

Look for proof of hands-on experience with Katalonโ€™s specific features and workflows. Uma can run instant video interviews and build shortlists with side-by-side comparisons to speed up your review. Focus on candidates who show structured test assets and clean integration patterns.

  • Check portfolios for organized test suites and reusable custom keywords that reduce script duplication.
  • Verify experience with Katalon TestCloud or TestOps for scalable execution and result management.
  • Confirm familiarity with version control systems like GitHub for collaborative test asset maintenance.

Step 3: Interview your top choices

Discuss technical approaches to ensure the candidate matches your project complexity. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session. Ask about their problem-solving methods for flaky tests or complex object recognition.

  • Ask how they handle dynamic web elements and implement robust object identification strategies.
  • Request examples of how they structured data-driven tests for varied input scenarios.
  • Discuss their process for debugging failed test runs and reporting defects to development teams.

Step 4: Agree on scope and begin work

Set clear deliverables and milestones before starting the engagement. Use Upwork Messages and the contract workroom for all communication and project management tasks. Upwork verifies identity, offers hourly tracking, and holds project funds for security.

  • Define specific test cases to automate and set acceptance criteria for pass rates.
  • Agree on the delivery format for custom keywords and integrated CI/CD pipeline scripts.
  • Establish a schedule for regular test execution reports and defect logging updates.
